Electric bus technology is gaining popularity in Europe due to efforts to improve air quality and reduce greenhouse gas emissions. Several cities, including London, have seen thousands of premature deaths per year due to poor air quality. London aims to transition to a zero-emission bus fleet by 2037. The electric bus market in Europe is growing rapidly, with orders increasing and market share projections showing electric buses will dominate by 2025-2030. Several European cities have pledged to transition their bus fleets to zero-emissions by certain dates. Battery technology continues to develop quickly, lowering costs and increasing range, though ensuring battery supply and mitigating risks like fires remain challenges.
